Title: Desiliconizing method for chromium-containing molten iron
Inventor: KAMEGAWA KENICHI
IPC: C21C7/00
Filed: 1985-06-05
Abstract: PURPOSE:To desiliconize effectively a chromium-contg. iron contg. a specific ratio of C and Cr without using an oxidizing agent by determining slag basicity from a specific element and adjusting the slag basicity so as to make larger the same larger than the determined value in the stage of desiliconizing the above-mentioned iron. CONSTITUTION:The chromium-contg. molten iron contg. 1-3% C and 2-35% Cr is desiliconized in an arc type electric furnace or AOD furnace. The slag basicity at which the desiliconization reaction and decarburization reaction by the chromium oxide between slag and metal at the target Si value of desiliconization attains the equib. is determined from the temp., component compsn. of the chromium-contg. molten iron to be treated and the partial pressure of CO. The slag basicity is then adjusted by the addition of lime, etc. so as to attain the value larger than the determined value by which the activity of SiO2 in the slag is decreased. The reduction of the Si in the molten iron to about <=0.05% is thus made possible.

Abstract: PURPOSE:To prevent the dropping of an inductance caused by the magnetic saturation of an iron core so as to prevent the occurrence of a resonance phenomenon caused by harmonics by shunting a rush current generated when a capacitor is started to a by-pass circuit connected in parallel with a series reactor. CONSTITUTION:Circuits respectively constituted by connecting in series nonlinear resistance elements NLR made of zinc oxide, etc., and current limiting resistors LR are connected in parallel between the terminal of each phase of a series reactor L. When the circuit voltage is, for example, 6,600V, nearly the full voltage of a 3,810-V phase voltage is applied across the terminals of the reactor L at the moment a capacitor C is actuated. When the varistor voltages of the nonlinear resistor elements NLR are about 500V, the elements NLR are set to non-conducted states at such a low voltage and, when the resistances of the resistors LR are set at levels which are sufficiently lower than the reactance of the reactor L, most of a rush current is shunted to the by-pass circuits composed of the elements NLR and resistors LR.
